What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests a personalized, digitally supported prehabilitation program for adults waiting for elective cardiac surgery. Participants receive education, psychosocial support, nutritional advice, and home-based exercise guidance during the routine 6-10 week preoperative period. The goal is to see if this program is feasible, acceptable, and safe to integrate into standard care, with exploratory outcomes on functional capacity and well-being.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
a personalized, multimodal, digitally supported prehabilitation program including education, psychosocial support, nutritional counselling, and home-based physical activity guidance
What this could lead to
If successful, this approach could improve recovery and outcomes for people awaiting cardiac surgery.
What could go wrong
This is a small feasibility study, so results may not apply broadly, and the program may not be practical or effective in routine care.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 40 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

Aug 2026

An estimate. Start dates often move.

Expected to finish

Oct 2027

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.
